For about 2,000 years – since Roman emperor Tiberius demanded fresh cucumbers for lunch year ‘round – farmers have been looking for better ways to extend the growing season. Now, a team of researchers led by Purdue University has found a way to grow more produce and save money doing it.
Greenhouses and other structures protect crops from harsh environmental conditions. Over the last 50 years or so, some growers have added artificial lighting to compensate for shorter winter days or when conditions are cloudy. However, the problem with most lighting systems is that they are relatively costly to install and do not provide the light spectrum that is most efficient for photosynthesis in plants. Read more »
Did you throw away any food today? If so, you are not alone.
Many of us struggle to store or use up the last of the leftovers or think of something edible to do with those shriveled vegetables at the bottom of the chiller drawer. In fact, in 2010, 133 billion pounds of food in U.S. retail food stores, restaurants, and homes never made it into people’s stomachs. An estimated 30 to 40 percent of the food supply in the U.S. is wasted, in that it never reaches the intended consumers. Unfortunately, the decision to purchase and then discard food has some serious ramifications for the environment and for food security.
Together, we can do something about this. On June 4th – the day before World Environment Day – USDA and the U.S. Environmental Protection Agency will launch the U.S. Food Waste Challenge and call on organizations spanning the food supply chain to join the fight against food waste. Together we can help reduce the amount of food that is sent to our landfills and increase the amounts that are recovered to help families in need. Read more »

As America marks the 40th anniversary of the first Earth Day, it’s good to reflect on the real, positive affect USDA’s water program and the American Recovery and Reinvestment Act (Recovery Act) is having on rural Alaska. Our Department, working with other Federal departments and the State, continues to fund projects to improve water quality across Alaska. Here’s an example: Read more »
